This is according to a new independent report The British Gas Home Energy Report 2011, by the Centre for Economics and Business Research (Cebr) and based on 40 million British Gas meter readings over a four year period. All the figures are weather-adjusted to show underlying trends in consumption.
The report finds customers who adopted simple energy efficiency measures such as insulation and energy efficient boilers saved an average of £322 each year, and saw a 44 per cent fall in their gas use between 2006 and 2010, but some homes took no action at all.
Gearóid Lane, Managing Director of British Gas New Markets, said:
"£1 in every £4 spent on heating our homes is wasted because of poor insulation. We want to help as many of our customers as possible reap the benefits of more energy efficient homes. That’s why we’re launching a national programme to give our dual fuel customers access to free cavity wall or loft insulation.
"Rising global energy prices needn’t mean higher bills for households. This report shows that many homes are already reducing their energy consumption and cutting bills, but we want all British Gas homes to enjoy the same benefit."
Jonathan Thurlwell, Director of Competition Economics at Cebr, who produced the report for British Gas said:
"This report represents the largest independent analysis of domestic natural gas consumption representing nearly a fifth of the entire national market. Using detailed modelling techniques we were able to determine that energy efficiency measures are the primary driver of the average annual decline in underlying gas consumption. The message is clear: in a global environment of rising commodity prices the most effective way for households to reduce costs is through basic energy efficiency measures."
